- Abstract
In November 2017, a 15-day-old calf located in France (Haute-Savoie department) was found positive for bluetongue virus (BTV) RNA by RT-PCR. Laboratory investigations allowed the isolation and identification of the serotype: BTV-4. The analysis of the full viral genome showed that all the 10 genome segments were closely related to BTV-4 strains involved in a large BT outbreak in the Balkan Peninsula, in Italy since 2014 and in Corsica since the end of October 2016. These results together with epidemiological data suggest that BTV-4 has been introduced to mainland France from Corsica or Italy where BTV-4 outbreaks have been reported in summer and autumn 2016. This is the first report of the introduction of BTV-4 in mainland France., (© 2018 Blackwell Verlag GmbH.)
